The basic motion of the vibratory trough, or work member, is a controlled directional linear vibration which produces a tossing or hopping action of the material. Material travel speeds vary from 0 to approximately 100 ft. per minute, depending on the combination of frequency, amplitude, and slope vibration angle.

Vibration can be expressed in metric units (m/s 2) or units of gravitational constant "g," where 1 g = 9.81 m/s 2. An object can vibrate in two ways: free vibration and forced vibration. Free vibration occurs when an object or structure is displaced or impacted and then allowed to oscillate naturally.
